The quark composition of a deuterium nucleus is 3 up quarks and 3 down quarks. The overall charge of the deuterium nucleus is +1. Comparing the given overall charge to the chart of the Particles of the Standard Model, the overall charge can be determined from the combinations from the choices. Among them, only C gives the correct overall charge.

Answer:

Option (c)

Explanation:

One up quark = $+\frac{2e}{3}$

One down quark = $-\frac{e}{3}$

One proton is having one e charge.

The quark composition of proton is 2 up quark and one down quark.

The quark composition of neutron is one up quark ad two down quark.

Thus, the quark composition of nucleus of deuterium is

2 up quark and one down quark + one up quark and two down quark

So, it is 3 up quark and 3 down quark.

What does one prolonged blast emitted by boat a using an efficient sound producing device indicate?

Anika [276]

A single prolonged blast emitted by a boat using an efficient sound producing devices indicates that the boat is leaving the dock. It may also be used to indicate that the boat is moving and for alarming other vessels, but in this case, one prolonged blast is followed by two short blasts, in two minutes of time.

The mass of your new motorcycle is 250kg. What is the weight on the moon in newtons

Hunter-Best [27]

Weight of motorcycle on the moon = mg

Here, g= 1.622 m/s²

So, W = 250 * 1.622 = 405.5 Kgm/s² = 405.5 N.

The drill used by most dentists today is powered by a small air-turbine that can operate at angular speeds of 350000 {\rm rpm} .

damaskus [11]

Answer:

5833.33

Explanation:

$\alpha$ = Angular acceleration

$\theta$ = Number of revolutions

$\omega_i$ = Initial angular speed = 0

t = Time taken = 2 s

Final angular speed

$\omega_f=\dfrac{350000}{60}=5833.33\ rps$

From the equation of rotational motion we have

$\omega_f=\omega_i+\alpha t\\\Rightarrow \alpha=\dfrac{\omega_f-\omega_i}{t}\\\Rightarrow \alpha=\dfrac{5833.33-0}{2}\\\Rightarrow \alpha=2916.665\ rev/s^2$

$\theta=\omega_it+\dfrac{1}{2}\alpha t^2\\\Rightarrow \theta=0\times t+\dfrac{1}{2}\times 2916.665\times 2^2\\\Rightarrow \theta=5833.33\ rev$

The number of revolutions is 5833.33

One of the foci for the moon's orbit would be the

suter [353]

The question is oversimplified, and pretty sloppy.

Relative to the Earth . . .
The Moon is in an elliptical orbit around us, with a period of
27.32... days, and with the Earth at one focus of the ellipse.

Relative to the Sun . . .
The Moon is in an elliptical orbit around the Sun, with a period
of 365.24... days, and with the Sun at one focus of the ellipse,
and the Moon itself makes little dimples or squiggles in its orbit
on account of the gravitational influence of the nearby Earth.

I'm sorry if that seems complicated. You know that motion is
always relative to something, and the solar system is not simple.
